Classroom Display Instructions and Tips

UNIT’s Classroom Technologies group installs, upgrades, maintains and supports multimedia and Audio/Video presentation equipment in all registrar booked general classrooms as well as many labs, conference rooms and event spaces on campus.

These rooms are equipped with projectors and/or displays for presenting computer generated content. As a BYOD campus it is important for users to connect their devices to the existing wired AV systems and the growing number of wireless AV solutions. These instructions can help you get connected to the projector in wired classrooms on campus. If you are using a wireless display system please see the AirMedia section below to connect to a wired AV system.

All of our classroom AV systems have a color coded cable system. This makes it simple for any user to connect to the AV system without having to know the technical name of the cable or connection they need to use. All of our classroom AV systems are coded using the following colors:

Orange – HDMI

Yellow – Mini DisplayPort

Blue – VGA

Have you ever experienced a problem getting your laptop or mobile device to display on the classroom display? The connection sequence when connecting to an AV system is very important. Below is the recommended sequence for connecting your device to any AV system:

1) Make sure the laptop and AV system are turned off.

2) Connect your laptop or device to the AV system.

3) Turn on the AV system.

4) Turn on your device.

5) Use the proper key commands to duplicate or extend your laptop display to connect to a wireless AV system

Using AirMedia Instructions

Do you remember a few years ago when your cable provider made a change from broadcasting analog signals in favor of digital signals? The same transition is happening in the AV industry and it will affect all consumer and commercial electronics products in the marketplace. The Analog Sunset refers to a portion of the Advance Access Content System (AACS) license agreement adopted by content owners and device manufactures to insure copyright protected content, such as motion pictures, is not illegally copied and distributed. High-Bandwidth Digital Content Protection (HDCP), along with a license obtained from the Digital Content Protection, LLC helps prevent the stealing of data. What does this mean for you? The VGA (blue) connection in classroom AV systems will begin to be phased out as computers, displays and other AV equipment no longer have or support this analog connection.
